Flexor and Extensor Muscles

Topic: Flexor and Extensor Muscles

Question: Which muscles are stronger, flexor or extensor muscles?

Hypothesis:My hypothesis is that each member of the group's flexor muscle will be stronger than the extensor muscle.

Procedure:

1. Get into groups
2. Have one person stand up straight with his / her back against a wall.
3. Have that person hold the weights in his / her dominant hand
4. In a "curling" motion, have the student raise and lower the weights until his / her arms get tired.
5. Repeat steps 2-4 for each member of the group.
6. Record the data for each member of the group.
7. Have the first person stand as straight as possible near a wall.
8. Have the student hold the weights with his / her dominant arm bent near the ear.
9. In a motion that mimics throwing, have the student extend the weights above his / her head until the dominant arm gets tired.
10. Repeat steps 7-9 for each member of the group.
11. Record the data for each member of the group.

Data:
Conclusion: In my hypothesis I stated that the flexor muscle was going to be stronger than the extensor. Boy was I wrong. The extensor muscle was stronger than the flexor muscle. The total average for the flexor muscle was 40.2 and the total average for the extensor muscle was 50.28.
